Telephone handle test
The telephone is composed of three parts: call device, signal device and conversion device. The quality of the telephone not only affects its use, but also affects the communication quality of the whole process and the entire network. Therefore, it is very important to detect it and achieve the specified performance indicators. It is necessary to use a special electroacoustic tester for quantitative testing. Make a reliable guarantee for product quality.

Telephone Handle Test
Connect the handset of the telephone under test to CRY6151B DUT MIC (headset) / HEADPHONE 1 (receiver)
CRY6151B makes the mouth simulator sound through MOUTH1 port-> DUT MIC interface microphone to acquire sounds -> input into CRY6151B for analysis
CRY6151B uses the HEADPHONE 1 to output audio and make the receiver under test sound -> the ear simulator microphone to acquire sounds -> input into CRY6151B for analysis
Telephone speaker test path
Connect the SPK of the telephone under test to CRY6151B HEADPHONE 1 output
CRY6151B uses the HEADPHONE 1 to output audio and make the SPK under test sound -> the ear simulator microphone acquires sounds -> input into CRY6151B for analysis
